摘　　要：将在2.5 g的KMnO_4,5%的DMF水溶液,水热温度120℃,水热时间24 h条件下制备的纯相γ-MnOOH作为锰源,与LiOH·H_2O水热后煅烧制得了尖晶石结构的Li_(1.6)Mn_(1.6)O_4,酸浸洗脱后的离子筛MnO_2·0.5H_2O饱和吸附量为27.38 mg/g,Mn^(2+)的溶损为5.3%。The pureγ-MnOOH could be obtained at 120℃for 24 h with the mixed solution of 5%DMF and 2.5 g KMnO4,which was used as source of manganese to hydrothermal react with LiOH·H2O and then prepared the spinel structure Li 1.6 Mn 1.6 O4 via calcination.After acid treatment,the maximum adsorption capacity of MnO2·0.5H2O ion sieve was 27.38 mg/g and the dissolution of Mn 2+was 5.3%.
